Maase@ @y @anni l @Bifida NOEAL MAY 'AND HENRY F. STIVERS, OF SAN FRANCISCO, CALI- FORNA.

Letters Patent No. 864024, dated January 19, 1869.

The Schedule reened to in these Letters Patent and making part of the same.

` To all whom it may concern Be it known that we, NOEAL Mar and HENRY F. STIVERS, ofthe city and county of San Francisco, State of California, have .invented an`Improvcd Device for Burning Petroleum 5. and We do hereby declare that the following description and accompanying drawings are Sufficient to enable any person .skilled in the art or science to which it most nearly appertains, to make and use our said invention or improvements without further invention or experiments.

The nature of our invention is to provide an improved device for the more perfect and even combus- `tion of petroleum, for thel generation of steam, cooking,

4household, and Warming-purposes; and consists in in'- troducing into the'ire-box, chamber, or furnace, cold water, combined with the oil, the supply of each being regulated from the tanks or reservoirs by stop-cooks, so that as' the oil rises to the top of the water,and forms the fire-surface, and combustion takes place, the temperature of the water beneath the burning oil-may be` regulated by supplying and discharging, to prevent the generation of steam, which may otherwise arise and put out the ilame.

Our invention also relates to the introduction of steam for the quick drawing or extinguishment ofthe res in the re-box or furnace.

To more fully illustrate and explain our invention, reference is had to the .accompanying drawings, and .letters marked thereon, of which-4 Figurel 1 is a side elevation.

Figure 2, a plan.

Figure 3 shows the tire-bok` or furnace in section, supply and ind notion-pipes.

Similar letters indicate like parts in each of the figures.

A is the oil-tank or reservoir, and

B, the Water-tank, which are placed at a suitable elevation above the furnace, to obtain the desired fall.

Branch-pipes, C C', lead from each of the tanks, provided with stop-cocks D D', and connect with the main pipe E, which opens into the fire-box, near the bottom.

About midway between the fire-box and the branchconnection of the main pipe, is a stop-cock, E,-for shutting oi" both the supply of water andv oil from it.

The lire-box or furnace F is simply a square or oblong box, or it may be constructed in any shape to vsuit the apparatus to be heated, and is provided with stopcocks G G at the end and side, which admit of rapidly drawing off the contents of the box. y

At the front end is attached a perforated plate, H, through the openings of which air may be admitted, and the state of combustion observed.

A sliding plate or door, H', is placed over the per-v brated plate, and which mayA be partially opened or Wholly closed, at will. It may be found necessary to close it entirely when suddenly extinguishing the lires.

The boiler or other apparatus to be heated is placed over the top of the box or furnace, and rests on its edges, and should have an air-tight connection, by cementing or masonry, leaving a sufficient opening at the necessary point for a flue.

Pipes I I cxtendupward from each side of the box, and communicate with the steam-surface of the boiler, and are provided with stop-cocks, which, by turning, will admit steam into the' amesand draw the fires quickly.

To the end of the supply-pipe, in the fire-box, is a tached, by a screw-coupling, a chamber, J, which has several short pipes, a a a a, extending from it. Through these pipes the water" and oil issue,mixed in the rela tive proportionsdesired as it cornes from the tanks.

It would be advisable, inxstarting the apparatus, to `first admit water from the water-tank in a sueient quantity to cover the chamber and induction-pipes' in the fire-box, after which the water and oil may flow in together through the main or supply-pipe, the quantity of each being regulated by means ofthe stop-cocks in the branch-pipes.

Gare should be taken to keep the Awater beneath the i burning oil at such a temperature as not to generate steam, or too much moisture, as that will stop combustion yby putting out the lire.

B'y this means crude petroleum may be easilyand economically employed for generating steam and other purposes, as well on the sea as on the land.

As far as our expeiience has extended, salt water maybe used with the oil, and with as signal success as when fresh Water is employed, as the oil rises to the top of the water somewhat puried by its bath, and the sediment settles to the bottom of the fire-box, to be drawn off with the water.

Having thus described our invention,

What We claim, and desire to secure by Letters Patent, is

1. Mixing the oil and. water by means of the branchpipes G C', at the junction of the main pipe E, before it'enters the rire and water-box or furnace, and the stop-cocks D D', for regulating the relative quantity of water and oil, substantially as described.

2. The hydrocarbon-burners, described, consisting of the tanks A B, pipes O C', uniting in main pipe D, chamber J, with pipes a a, furnace F, with cooks G and plate H, the whole being constructed and arranged as described, for the purpose set forth.

In witness whereof, we have hereunto set our hands and seals.
